Maximum PVC Service Temperature 140°F
Pressure De-rating at Elevated Temperatures
The pressure ratings given above are for water, non-shock, @ 73°F. The specified derating factors
for PVC are suitable for pipe conveying water at elevated temperatures. To determine elevated
temperature rating, multiply 73°F [23°C] pressure rating by appropriate factor shown in the table
for desired operating temperature. When working near maximum specified temperature, solvent
cement joints are recommended in place of threaded connections. Where disassembly is required
at elevated temperatures use Spears® Special reinforced (SR) adapters, flanges, unions or grooved
coupling connections. Spears® recommends that only Schedule 80 or heavier wall thickness pipe
should be threaded.
